I decided to make this guide for people who like to play multi player games with other people, but dont always have 2 copies. 1. Start the game ( We are using Metal gear, Po. for this Example) Go into multiplayer as you always would,select adhoc. 2. Create the game, enter it normally. 3. Pause it so the clock wont run down. 4. Take the game out of the hosting psp and put into the empty one. Navigate to the ad hoc lobby and select the hosting psp's game. 5. Once you are in, you might have to swap games quickly sometimes( after killing someone, or whenever the game freezes) 6. HAVE FUN!
